Certification Providers
The Certified ScrumMaster (CSM) is offered by Scrum Alliance, while the Professional Scrum Master (PSM) is provided by Scrum.org. Each organization has its own certification process and governance.
Exam Format and Difficulty
CSM requires attending an in-person or live online course before taking the exam, which is relatively easier and consists of multiple-choice questions. PSM does not require mandatory training and its exam is more challenging with a higher passing score and a mix of multiple-choice and open-ended questions.
Training Requirements
For CSM, candidates must complete an official Scrum Alliance course conducted by a Certified Scrum Trainer. PSM candidates can self-study and directly take the exam, though Scrum.org recommends training.
Cost Differences
CSM certification generally costs more because it includes mandatory training fees, which can be several hundred to over a thousand dollars. PSM exam fees are lower since training is optional and the exam can be taken independently.
Certification Levels
Scrum Alliance offers a multi-level CSM path including Advanced ScrumMaster (A-CSM) and Certified Scrum Professional (CSP). Scrum.org offers PSM I, PSM II, and PSM III for increasing levels of mastery and expertise.
Renewal and Continuing Education
CSM certification requires renewal every two years with continuing education and a renewal fee. PSM certification is lifetime with no renewal or additional fees after passing the exam once.
Focus and Approach
CSM emphasizes practical Scrum implementation and team facilitation skills through its mandatory courses, targeting those who are new to Scrum roles. PSM focuses more on understanding Scrum theory and principles, testing thorough knowledge of the Scrum framework.
Recognition and Industry Perception
Both are globally recognized, but Scrum.org certifications (PSM) are often viewed as more technically rigorous. CSM is popular among organizations valuing hands-on training and practical Scrum coaching.
Exam Retake Policy
CSM typically allows several retakes after completing additional training or waiting periods, depending on Scrum Alliance policies. PSM allows multiple exam attempts by paying the fee each time, with no mandatory training prerequisites.
Community and Support
Scrum Alliance offers a large community with local user groups, events, and mentorship opportunities. Scrum.org provides online forums and resources but has a smaller focus on community networking compared to Scrum Alliance.
